SUNSCREEN APPLICATION ADVICE

Even if you use sunscreen regularly, you may be among the one-fourth to one-half of sunscreen users who use inadequate amounts. If so, your sunscreen may not be as effective as you think. For instance, when a sunscreen with an SPF of 16 is put on too sparsely, it may only provide SPF 2 protection. To avoid this problem, start with a sunscreen with an SPF of 30 or higher, and use about two tablespoons (one ounce) to cover your entire body. One-quarter to one-third of a tablespoon is about the right amount for covering the face. Sunscreen should be applied about fifteen minutes before going out in the sun, and it should be reapplied every couple of hours.

Most skin cancers can be prevented by wearing the right amount and SPF level of sunscreen and wearing protective clothing such as hats with brims.  Pay attention to any change in appearance of moles on your skin.  At ELMHURST DERMATOLOGY, we incorporate the most advanced diagnostic methods for skin cancer.  We also treat skin conditions such as psoriasis, eczema, and atopic dermatitis.  Please call us at 630-832-2111 to schedule an evaluation.  Our office is located at 103 N.

P.S. On cloudy or overcast days, about 70 to 80 percent of ultraviolet radiation pierces the clouds, causing  photo damage to the skin (premature wrinkling, age spots, dryness, and a variety of skin cancers).

NO RELIABLE SHORTCUT TO MELANOMA DIAGNOSIS

As smartphone applications abound and users increasingly rely on them to perform tasks ranging from conducting vision exams to keeping track of calories consumed, dermatologists strike a note of caution. According to research involving four smartphone applications that claim to be able to distinguish between benign lesions and melanoma, results were found to be “highly variable.” Interestingly, three of the apps relied on algorithms to make the determination, while the fourth relied on a remote evaluation by a dermatologist. The diagnosis success rate ranged from 6.8% to 98.1%, with the highest score coming from the dermatologist. This study shows that something as important as a melanoma diagnosis should not be left to anyone (or thing) less than a professional dermatologist.

Technology has changed how we gather information.  However, a smart phone application is not a substitute for a board certified dermatologist.  If you notice unusual moles on your skin or experience skin discomfort, please call ELMHURST DERMATOLOGY at 630-832-2111 to arrange an evaluation.  We follow the latest medical standards and create customized, comprehensive treatment programs.  Our office is located at 103 N. Haven, Suite 7, Elmhurst.  We strive to provide the highest quality care to our patients

P.S. The three melanoma-diagnosing apps generated by algorithm mentioned above missed the diagnosis on 30% or more of actual melanomas, classifying them as “unconcerning.”
